Re. 19,346-v DFFICE This` inventionrelates. to a-.clip construction mg posite sides of the body portion for gripping the materialy between two slotted portions of the Writingv instrument, the body portion being of. va resilient material and bent so as to urge the ballshaped end into engagement with the body por i ofy the barrelof the pencil or vcap of then fountain pen.

The present invention obviates the necessity of securing` the: clip-l to the casing with the use of solder,.-screws; rivetsror the likel and presents: al wsmooth and unobstructed inner surface in the easing whereby the inner mechanisms; suchas the'lead--; propelling mechanism ofv the mechaniy calpencil,t or the rubber insert for sealingV the ink feeding mechanisrnofy the pen, encounterv ,noy interference Within the casing.- t f Pencils and fountain pens, of present construction are general-ly formed:- of' compositionssuch ase-are" known'tothe trade.- as Raclitex.y bakelite1 a-ndr the Thetrend' is toward thin models: of 3, writing instrumentsand in"y order that the construction be. durable at the same time, either the` composition, shouldy be of comparatively great. thickness or should'be reenfrcedif comparative.-L ly thin.

Y The .leadmoifin'gf mechanism is anchored. in the lower 'on writing endfporticnfof the Vtwo-part andi: has. 2a..,pozftic1'rz.A extending.' outwardly 110 therefrom for engagement in a sleeve 10a anchored in the upper end portion of the casing. The sleeve 10a is provided with longitudinally extending ridges spaced peripherally thereof for engaging registering. ridges nthe outer Wall of the tube. or r outwardly extendingoperating. portion ofthe lowercasing. 'I'he sleeve 10a not an essential feature of the present invention andl is shown merely for the purpose of disclosing more clearly the unobstructed inner surface whereby the lead propelling mechaniSmencounters no interference within the casing for operation.

The clip which together withl the Yaferedescribed nally of the bodyportion and are bentsubstan-l tially at right angles thereto in the initial condition thereof. The ears 17 and-,18 are adapted tov be inserted through the openings 13 and. 14,

301 respectively, in the casing and are bent toward eachother to lcontactwith and toY cover the un-' dersideof thev material between the slots with their projecting edges substantially. meeting. By reason of the ears being relatively thin, al minimum of space is occupied within the kcasing yet providing for a sucient strength of thelmaterial of the body portion which ishthickened-'relatively thereto. In clamping the ears 17 and Y13 over the material lof the casingthe material'of the metal shell 10 between the slots is urged toward the body-portion 1,5 of theclip to form a raised longitudinally extending strip and the material of the composition shell 11 is preferably compressed therebetween in .order that the inner surface of the casing be preservedin a smooth, unobstructed state, the bottom surfacesof the. projecting edgesof the ears 17and` 18 extending flush vwith the periphery of the circular bore of the shell 10. 'It will be noted that in order to provide a neat appearing pencil or other writing instrument, the

slots or openings 13 and 14 must be comparatively` close together in order that a clipof a medium width `of the pencil may be employed. .Byreason of the openings 13 and 14 beinglrthus close toto retain the clip thereon, even though the writing instrument be knot misused. Therefore, the 60,; inner shell 10 being ofvmetal acts as a reenfjorcement for they composition shell generally-4 and. provides an efficient-gripping means A,for retaining. the clip against displacement specifically.

In providing. the present construction there are but'two operations necessary,` one in which'the apertures 13 and 14 are formed either by means of a rotary cutting instrument or a punch, andV the second in which: the ears are bent toward each other and toward the body portion 15 of theclip tures of the metal shell. 10.. Referring, now moreparticularly toFig. 7, the construction shown is that of a cap formed-of composition, :therthickness ofthe composition gether the material of the composition between the openings in and of itself wouldhardly sumcek to compress the material of the compositiony shell` 11 Vand to raise the Amaterial between the aper- -side thereof, is disposed between the ears as the latter are inserted through the openings 13 and 14, whereafter the ears are bent inwardly toward each other in the manner previously described with reference tothe prior embodiment whereby the composition material is preferably compressed between the body portion 15 of the clip and the ears 17 and 18 thereof and the reenforcing strip 19 is raised to seat itself within the composition material allowing sufcient room for the ears to clear the inner bore of the cap. Therefore, the sealing member 20 for the ink feeding mechanism may be 'inserted intothe cap 'without interference. It `is to be noted that shouldV the ears 17 and 18 and/or the reenforcing strip 19not clear the inner bore of the cap vbut extend there`` into substantially, the sealingmember'ZOfwould 100 of necessitybe cut away in a mannerto permit clearance of this obstruction. This, rof course, would be greatly objectionable.

-As a result of this invention a means has been: provided for securingclips to casings of various types for writing instruments, the casings being of a composition material wherein that material is suitably reenforced to provide'a substantialsupport for theclip. The construction also provides for a minimum number of operations in as's'embling the construction, which, of courserreduces the cost of construction and naturally provides a more eicent and durable construction, there being less chance of crystallzation of the material. The clip is secured'to the writing instrumentl` without the use of solden-screws, rivets or the likeandv thus preserves a smooth and unobstructed inner surface of the casingrwhereby the sealing member for fountain pens or the lead propelling, repelling or expelling mechanism avoids interm ference inthe'casing. l i f 1i' While but two forms of this invention are herein shown and described, it is to be understoodthat various ymodifications may be apparent to those skilled in the' art without departing'from the spirit 125 and scope of this invention and, therefore, the saine is to be limited only by the scope of the prior art and the appended claims.
